  • Publication number: 20200108337
    Abstract: A filter arrangement for liquids has a filter housing and a functional carrier arranged inside the filter housing. A cylindrical filter element is inserted axially into the filter housing and defines an unfiltered side and a filtered side inside the filter housing. A non-return diaphragm is arranged on the filter element within the filter housing, wherein the non-return diaphragm is connected to the functional carrier and held at an axial spacing against a stop of filter housing so as to effect an axial and/or radial sealing action of the unfiltered side relative to the filtered side of the filter arrangement.

  • Patent number: 7513373
    Abstract: A filter element (10) suitable for installation in a liquid filter for cleaning a freeze-endangered liquid; the liquid filter having a housing (37), composed of a housing pot (38), a housing cover (39), and a filter element (10) situated in the housing pot (38), with the housing cover (39) screwed onto the housing pot (38) in a sealed manner. The filter element (10) has a first end disk (11); a second end disk (12), and a filter medium (13) interposed between the end disks (11, 12). The end disks (11, 12) are mutually connected by a supporting element (30), which prevents radial relative movements between the end disks (11, 12). In the axial direction, the supporting element (30) has snap hooks (25) which connect the first end disk (11) undetachably to the second end disk (12). As a result of this connection, the second end disk (12) can be reliably removed from the housing pot (38) by pulling on the first end disk (11).

  • Patent number: 7323102
    Abstract: An apparatus for filtering a liquid, with a housing, a liquid inlet arranged in the housing, a liquid outlet arranged in the housing, a filter for removing particles from a liquid stream arranged between the liquid inlet and the liquid outlet, and at least one additive for functionally altering the liquid properties arranged in the apparatus, in which the additive is arranged in the interior volume of the apparatus and is shaped in a colloidally disperse, dimensionally stable, elastic form corresponding to at least one geometric space defined by an interior structure of the apparatus or of the filter for removing the particles.

  • Publication number: 20050263451
    Abstract: The inventive filter element (10) is suitable for installation in a fluid filter which is provided for cleaning a freeze-endangered fluid. The fluid filter has a housing (37) with a housing pot (38) and a housing cover (39). The filter element (10) is situated in the housing pot (38), with the housing cover (39) being screwed to the housing pot (38) with a seal. The filter element (10) has a first end disk (11) and a second end disk (12), a filter medium (13) being introduced between the end disk (11, 12). The end disks (11, 12) are mutually connected by a supporting element (30), the supporting element (30) preventing radial relative movements between the end disks (11, 12). In the axial direction, the supporting element (30) has snap hooks (25) which connect the first end disk (11) undetachably to the second end disk (12). Due to this connection, the second end disk (12) can be reliably removed from the housing pot (38) by pulling on the first end disk (11).
